Abstract

Rotor for a wind energy plant, comprising a hub (10), at least one rotor blade fixed to the hub (10) and a rotor blade adjuster device (30) comprising a pinion (40), wherein the pinion (40) is arranged to rotate the rotor blade by engagement with a crown gear arranged on the hub (10) or the rotor blade, characterised by guide means (50) for displacing the rotor blade adjuster device (30) between two positions, in which cooperation between the pinion (40) and crown gear is possible.
